What is especially hard to take on ALS is that a large number of cases are preventable. It is no accident that football players, soccer players at higher risk most likely secondary to head trauma. Even Lou Gehrig with frequent beaning by opposing pitchers. Not all cases with known head trauma but who hasn't hit there head at some point. Watching World Cup with the heading of balls shows we are not doing much to avoid this risk. Kids in school as well playing tackle football. Now more awareness of concussions and waiting for healing, but is that enough?
